Difference between transistor and vacuum tube?
They are both used for similar functions, such as oscillators, amplifiers, and switches. The vacuum tube was invented first, and has therefore been around longer than the transistor.
Why common emitter configuration is mostly used for transistor as switch?
because in ce configuration value of input voltage requried to make the transistor on is very less value of the output voltage or output current
What is the input impedance of an ideal voltage op-amp?
To get all the voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.

What is hie for a transistor?
hie is input impedance when signal applied at its base.
Is Common emitter configuration has high input impedance or medium input impedance?
Slightly less than cc configuration but greater than cb
What is common collector?
A common collector, also known as an emitter follower, is a basic transistor amplifier configuration where the collector terminal is common to both the input and output. In this setup, the input signal is applied between the base and the emitter, while the output is taken from the emitter. This configuration provides high input impedance and low output impedance, making it useful for impedance matching and signal buffering. Additionally, it offers voltage gain close to unity, meaning the output voltage closely follows the input voltage.
What type of transformer configuration will you select to design a high input impedance and low output impedance amplifier?
main volage
Is input impedance of common emitter fixed quantity?
No, the input impedance of a common emitter amplifier is not a fixed quantity; it varies based on several factors including the transistor's characteristics, biasing conditions, and the values of the input resistors. Typically, it is influenced by the base-emitter resistance and the transistor's current gain (β). Additionally, external components in the circuit can further modify the input impedance. Thus, it is a dynamic value rather than a constant.
Why drain is called common in common drain amplifier?
The term "common" in a common drain amplifier refers to the configuration where the drain terminal of the transistor (typically a MOSFET) is connected to a common reference point, usually ground. In this configuration, the input signal is applied to the gate, and the output is taken from the source, making the drain the terminal that is common to both the input and output. This setup allows for a high input impedance and low output impedance, making it useful for various amplification applications.

What are the three basic transistor connection configuration modes?
The three basic transistor connection configuration modes are common emitter, common base, and common collector. In the common emitter configuration, the emitter terminal is common to both the input and output circuits, providing high voltage gain. The common base configuration has the base terminal common to both circuits, offering high frequency response but low voltage gain. Finally, the common collector configuration, also known as an emitter follower, provides current gain and high input impedance while maintaining unity voltage gain.
Why common emitter configuration is mostly used for transistor as switch?
because in ce configuration value of input voltage requried to make the transistor on is very less value of the output voltage or output current
Which is better high input impedance or low input impedance and why?
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
Why input impedance of FET is higher than ordinary transistor?
the gate is insulated from the channel by either a reverse biased junction or silicon dioxide.
Why you go for bootstrap circuit?
Bootstrapping is used to allow bias to be applied to the base of a transistor while maintaining a very high input impedance.
